As it stands now, either Dem wins against McCain. Keep in mind this is different than a single national opinion poll, some of which show McCain ahead. SurveyUSA's exercise here is to allocate electoral votes based on its state-by-state polls.

The interesting thing though is how close Obama and Hillary are to each other in electoral vote count. It's only a 4 vote difference, even though Obama carries far more states. The key difference? She takes Pennsylvania and Florida.
Late Update: Before the arrival of emails from supporters of each candidate, let me acknowledge that there is limited utility in this sort of exercise. Some state polls, for example, are within the margin of error, etc. But this is catnip for junkies.
